In the base 11, both end surfaces of the base convex portion 15 and the base concave portion 16 are located on the same plane. As shown in FIG. 3, in the base 11, a mounting protrusion 16 a extending outward is formed on the outer surface of the lower end of the base recess 16.

  As shown in FIG. 3, the engagement body 17 that can be attached to the cover recess 14 or the base recess 16 is formed of a synthetic resin material in a substantially U shape in front view. Specifically, the engaging body 17 made of a synthetic resin material has an inner peripheral surface of the engaging body 17 formed in an arc shape, and the length along the inner periphery is the circumference of the cover recess 14 or the base recess 16. It is formed longer than the length along the direction. Engaging protrusions 18 are formed on both side portions of the engaging body 17, and locking portions 18 a that protrude inward of the engaging body 17 are formed on the inner surface of the upper end of each engaging protrusion 18 in FIG. 3.

In FIG. 3, a planar portion S having a planar shape is formed on the lower surface of the engagement body 17, and an attachment hole 17 a through which the attachment protrusion 16 a can be inserted is formed in the central portion of the planar portion S.

  The engaging body 17 having the above-described configuration is attached to a base recessed portion 16 that is recessed on the outer surface of the base 11 as a recessed portion of at least one of the base 11 and the cover 12. In order to attach the engaging body 17 to the base recess 16, the engaging body 17 is mounted on the outside of the base recess 16, and the mounting protrusion 16a of the base recess 16 is inserted into the mounting hole 17a. Then, the engaging body 17 is formed into a base by heating and melting the tip of the mounting protrusion 16a that passes through the mounting hole 17a and protrudes to the outer surface of the flat surface S, and further solidifies the molten synthetic resin material on the flat surface S. The recess 16 is fixed to the base 11.

  Then, the engaging body 17 is attached at regular intervals or at arbitrary intervals along the length direction of the base 11, as shown in FIGS. As shown in FIG. 1, in a state where the engaging body 17 is attached to the base recess 16, both engaging protrusions 18 protrude upward from the opening edge of the base 11 from both sides in the width direction of the base 11. The stop portions 18 a also protrude upward from the opening edge of the base 11. As shown in FIG. 4, the outer surfaces of the engaging protrusion 18 and the flat surface portion S are formed at positions protruding outward from the outer surface of the base convex portion 15.

In the cover 12 and the base 11 configured as described above, the inner width of the cover recess 14 facing each other and the inner width of the base recess 16 facing each other _{are set to be the same.} Further, the cover convex portion 13 and the base convex portion 15 are formed to have substantially the same width direction dimensions, and the pitches of the cover convex portion 13 and the base convex portion 15 are configured to be the same. .

Next, the operation of the trough 10 will be described together with a method of forming the trough 10 using the base 11 and the cover 12.
In order to form the trough 10 by assembling the base 11 provided with the engagement body 17 and having the engagement protrusion 18 and the cover 12, first, as shown in FIG. Install in. In addition, you may fix the base 11 to a laying place using the fixing member which is not shown in figure. At this time, if the laying place is formed in a flat shape, the flat surface portion S comes into contact with the laying place, so that the base 11 is placed in a stable state. In addition, since the base 11 is easily bent at the uneven portion, the base 11 can be disposed in a slightly bent state along the wiring path of the cable K.

  Next, the cable K is accommodated from the opening of the base 11. Subsequently, the cover convex portion 13 and the base convex portion 15 are aligned, the cover concave portion 14 and the base concave portion 16 are aligned, and the cover 12 is pressed from above the base 11. At this time, since the cover 12 is easily bent at the uneven portion, the cover 12 can be assembled according to the bent state of the base 11. Then, both the engagement protrusions 18 are pressed outward from the inner peripheral surface side by the cover recess 14 corresponding to the base recess 16 to which the engagement body 17 is attached. Further, when the cover 12 is pressed downward, the engaging protrusions 18 return to their original shapes, and the inner peripheral surfaces of the both engaging protrusions 18 are arranged along the inner side surface of the cover recess 14.

  That is, the engaging protrusions 18 extending from both sides in the width direction of the base 11 are engaged along the outer peripheral surfaces on both sides in the width direction of the cover recess 14. As a result, as shown in FIGS. 2 to 4, the engagement protrusion is formed on the outer peripheral surface of the cover recess 14 as the other recess corresponding to the base recess 16 as the recess of at least one of the cover 12 and the base 11. 18 is engaged, and the base 11 and the cover 12 are assembled to form the trough 10.

  When the trough 10 is formed, the opening side end surface of the cover 12 is brought into contact with the opening side end surface of the base 11, so that the covering state of the cover 12 with respect to the base 11 is stabilized. Further, the base convex portion 15 of the base 11 and the cover convex portion 13 of the cover 12 have substantially the same dimensions. Therefore, the trough 10 is formed in a substantially square shape in front view by the base convex portion 15 and the cover convex portion 13, and is formed in a circular shape in front view by the cover concave portion 14 and the base concave portion 16.

  In a state where the trough 10 is formed, the engaging protrusions 18 enter the cover recess 14 and engage at a plurality of locations along the length direction of the trough 10. Therefore, even if a force that moves the cover 12 along the length direction of the base 11 acts on the cover 12, the outer surface of the cover convex portion 13 abuts on the outer surface of the engaging protrusion 18. The movement of the cover 12 in the direction is restricted.

  Further, as shown in FIG. 3, both engaging protrusions 18 are engaged along outer peripheral surfaces on both sides in the width direction of the cover recess 14. In the engaged state, the locking portion 18 a is locked to the outer peripheral surface of the cover recess 14 above the opening side of the cover recess 14. Therefore, the length of the straight line connecting the inner ends of the locking portion 18 a is shorter than the length of the straight line connecting the opening ends facing each other of the cover recess 14. Accordingly, the opening end side of the cover recess 14 is difficult to pass between the engaging portions 18a facing each other, the upward movement of the cover 12 is restricted by the engaging portion 18a, and the base 11 is connected to the base 11 by the engaging projection 18. Separation of the cover 12 is restricted.

  In addition, in a state where both the engaging protrusions 18 are engaged with the cover recess 14, both the engaging protrusions 18 are in continuous contact with the outer peripheral surfaces on both sides in the width direction of the base recess 16 and the cover recess 14. Yes. That is, the engagement protrusions 18 and the locking portions 18a are arranged so that the inner peripheral surfaces of both the engagement protrusions 18 and the locking portions 18a are pressed against the outer peripheral surfaces on both sides in the width direction of the base recess 16 and the cover recess 14. Is formed. Therefore, the opening of the base recess 16 and the cover recess 14 is restricted from expanding in the width direction of the base 11 and the cover 12 by the engagement protrusions 18.

According to the trough 10 of the said embodiment, the following effects can be acquired.
(1) The engaging protrusion 18 provided in the base recess 16 is formed so as to engage with the cover recess 14. Therefore, when the trough 10 is in use, the movement of the cover 12 in the length direction of the base 11 is restricted by the contact between the engagement protrusion 18 and the cover protrusion 13, and the cover 12 and the base 11 are moved in the length direction. Relative positional deviation can be regulated. Accordingly, the cable K can be reliably protected without the inconvenience that the cover 12 moves and the cable K protected in the trough 10 is exposed to the outside.

  (2) Further, since the engagement portions between the engagement protrusion 18 and the cover recess 14 are formed at a plurality of locations along the length direction of the trough 10, the engagement protrusion 18 and the cover protrusion 13 are formed. The contact position increases, and the movement of the cover 12 along the length direction of the base 11 can be effectively restricted.

  (3) Due to the engagement between the engagement protrusion 18 and the cover recess 14, the movement of the cover 12 along the length direction of the base 11 can be restricted. Therefore, in order to prevent the movement of the cover 12, post-processing after the formation of the trough 10 is not required, and the construction work of the trough 10 can be performed easily and quickly.

  (4) Since the base 11 and the cover 12 are each formed in an uneven shape along the length direction, the trough 10 is formed in an uneven shape along the length direction. Therefore, compared with the case where the trough 10 is formed in a flat plate shape along the length direction, the flexibility of the trough 10 can be improved, and the trough 10 can be bent and disposed. Therefore, the trough 10 can flexibly correspond to the cable K laying route.

  (5) An engagement protrusion 18 is formed by attaching the engagement body 17 formed separately from the base 11 to the base 11. Therefore, the position where the engagement protrusion 18 is formed can be changed to a desired position by adjusting the attachment position of the engagement body 17 with respect to the base 11.

  (6) The function of restricting separation of the base 11 and the cover 12 by the engaging protrusion 18 and the function of restricting the opening of the base 11 and the cover 12 in the width direction are exhibited. Can do. Therefore, the engagement protrusion 18 can exert the function of restricting the movement of the cover 12 in the length direction of the base 11 and the above two functions, and each function is provided by providing separate members. Unlike the above, the structure of the trough 10 can be simplified.

  (7) The engagement protrusion 18 engages with the cover recess 14, and the locking portion 18 a engages with the outer peripheral surface of the cover recess 14, so that the cover 12 can be easily detached upward in the base 11. The occurrence of inconvenience that the cover 12 and the cover 12 are separated can be prevented. Accordingly, it is possible to prevent the inconvenience of the cable K being exposed to the outside while maintaining the assembled state of the trough 10.

  (8) Engaging so that the engaging protrusions 18 are arranged on both sides of the opening side of the cover recess 14 and the base recess 16 to restrict the opening of the base 11 and the cover 12 in the width direction. can do. Accordingly, it is possible to prevent a gap or the like from being formed in the trough 10 while maintaining the state in which the opening side end surface of the base 11 is in contact with the opening side end surface of the cover 12. Therefore, it is possible to protect the cable K by preventing dirt and dust from entering the trough 10.

  (9) The base 11 can be stably installed at the place where the trough 10 is laid by the flat surface portion S of the engaging body 17. Therefore, when the cover 12 is assembled to the base 11, the cover 12 can be easily assembled without the base 11 rattling. Further, even after the trough 10 is formed, the trough 10 can be stably installed at the laying place.
